OREAS 751b has been prepared from a blend of spodumene concentrate derived from the processing of lithium pegmatite ores sourced from the Greenbushes area of southwest Western Australia, Londonderry lithium-pegmatite ore (containing elevated levels of lithium, rubidium, cesium, tin and tantalum), barren granodiorite and quartz. The barren granodiorite was sourced from the mafic, S-Type, Late Devonian Bulla Granodiorite complex located in northern Melbourne, Australia. The certification program includes:
